Abstract: For status that existing mine wireless communication systems had poor application effect in areas with severe environment and low-speed requirement of data transmission such as top corner, a scheme of applying LoRa technology in mine wireless communication was proposed through analyzing its technical characteristics. Application architecture of LoRa technology in coal mine was analyzed, and application situations were discussed. LoRa technology can wirelessly transmit equipment operation status data and environmental parameters in working face, multi-sensor data in mine pressure monitoring system, gas sensor data in top corner of working face, temperature sensor data in goaf, monitoring data of mine-used electromechanical equipment, etc.
